That question is stirring a lot of debate, but even Jaimee Grubbs, a 24-year-old cocktail waitress who says she had a 31-month relationship with the golf superstar, isn't sure.

JWOWW and Grubbs in the Club

Grubbs discussed her relationship with Woods from a downtown Chicago hotel Saturday hours before making an appearance at Manor nightclub.

"My personal opinion would be that he's not," said Grubbs. "The way that I was with him, and the way we were together, there was no sex addiction going on. But when I do read about these other girls and they talk in-depth about his party ways, that was never a side of him I saw, and the only way I could explain that would be that he does have a sex addiction."

Woods is rumored to have checked in to a Mississippi sex rehab clinic last week -- a good move, according to Grubbs.

"Rehab, therapy, whatever it may be, he needs something. He obviously has some personal issues he needs to deal with," she said.

About Last Night: Fashion Mashup

Grubbs is riding the wave this type of infamy brings, appearing in this month's Maxim magazine and hoping to springboard into an acting or modeling career. She has a new man in her life, who accompanied her on her trip to Chicago.

But what would she say now to the man she claims was her lover?

"I would kind of just tell him he sucks," Grubbs said.

"I didn't plan for it to turn out this way, and I'm moving on and I hope that he can just better himself and move on from it as well."
